Is there an animal which, both gives milk and lays eggs?

Yes, there are some animals that both give birth to live young and lay eggs. These animals are known as “ovoviviparous.” This means that while they do produce eggs, the eggs are retained inside the mother’s body until they hatch, and the offspring are then born live. This is a unique reproductive strategy that combines features of both egg-laying (oviparity) and live birth (viviparity).

One of the most well-known examples of an ovoviviparous animal is the platypus. Female platypuses lay eggs, but they retain the eggs in their burrows and provide care to the developing embryos until they hatch. The hatchlings are born as live young.

Certain species of sharks, such as some species of hammerhead sharks and some snakes, also exhibit ovoviviparity. In these cases, the mother retains the eggs within her body until they are ready to hatch, at which point the live offspring are born.

It’s important to note that the specifics of reproductive strategies can vary significantly among different species of animals, and not all members of a particular species may use the same method.
